1.0 WARRANTY INFORMATION

Patton Electronics warrants all Model 457B components to be

free from defects, and will—at our option—repair or replace the product

should it fail within one year from the first date of shipment.

This warranty is limited to defects in workmanship or materials, and

does not cover customer damage, abuse, or unauthorized modification.

If this product fails or does not perform as warranted, your sole

recourse shall be repair or replacement as described above. Under no

condition shall Patton Electronics be liable for any damages incurred

by the use of this product. These damages include, but are not limited

to, the following: lost profits, lost savings, and incidental or

consequential damages arising from the use of or inability to use this

product. Patton Electronics specifically disclaims all other warranties,

expressed or implied, and the installation or use of this product shall be

deemed an acceptance of these terms by the user.

1.1 RADIO AND TV INTERFERENCE

The Model 457B generates and uses radio frequency energy, and

if not installed and used properly—that is, in strict accordance with the

manufacturer's instructions—may cause interference to radio and

television reception. The Model 457B is designed to provide

reasonable protection from such interference in a commercial

installation. However, there is no guarantee that interference will not

occur in a particular installation. If the Model 457B does cause

interference to radio or television reception, which can be determined

by disconnecting the RS-232 interface, the user is encouraged to try to

correct the interference by one or more of the following measures:

moving the computing equipment away from the receiver, re-orienting

the receiving antenna, and/or plugging the receiving equipment into a

different AC outlet (such that the computing equipment and receiver are

on different branches).

1.2 CE NOTICE

The CE symbol on your Patton Electronics equipment indicates

that it is in compliance with the Electromagnetic Compatibility (EMC)

directive and the Low Voltage Directive (LVD) of the Union European

(EU). A Certificate of Compliance is available by contacting Patton

Technical Support.

1.3 SERVICE

All warranty and nonwarranty repairs must be returned freight

prepaid and insured to Patton Electronics. All returns must have a

Return Materials Authorization number on the outside of the shipping

container. This number may be obtained from Patton Electronics

Technical Service at

telephone: (301) 975-1007,

web address: http://www.patton.com;

Patton Electronics’ technical staff is also available to answer any

questions that might arise concerning the installation or use of your

Model 457B. Technical Service hours: 8AM to 5PM EST, Monday

through Friday.

3.0 CONFIGURATION

The Model 457B offers the option of configuring individual RJ-45

ports for specific twisted pair pin-outs. This section tells how to access

and set the internally mounted jumpers for each port.

3.1 DEFAULT SIGNAL-TO-PIN CONFIGURATION

The Model 457B is configured at the factory so that RJ-45 pin 4

corresponds to TIP and RJ-45 pin 5 corresponds to RING. This

default setting applies to the single host connection as well as the

seven terminal connections. Figure 1 (below) shows the pin numbering

scheme Patton follows with respect to the RJ-45 jack. If your wiring

scheme uses RJ-45 pins 4 and 5 in the manner described above, you

may move on to Section 4.0 Installation.

3.2 CHANGING THE SIGNAL-TO-PIN CONFIGURATION

If your RJ-45 twisted pair wiring scheme calls for pin-outs other

than TIP-4 and RING-5, you will need to re-configure the Model 457B

according to the following instructions.

1. Make sure the Model 457B's power is OFF.

2. Remove the two black Phillips head screws from the front of

the Model 457B and slide the PC board out of the case.

2.2 DESCRIPTION

The Patton Model 457B AllStar

is an active seven port

distribution hub for AS/400 and 3X systems. The Model 457B

distributes one twisted pair 1Mbps host to seven twisted pair 1Mbps

terminals. It is designed to be used in conjunction with Patton's Model

410 Series twinax baluns which adapt the host and terminal ports from

twinax to twisted pair.

The Model 457B features modular RJ-45 ports on the seven

terminal channels, and an RJ-45 port plus screw terminals on the host

channel. The host and terminal can be at distances up to 2250 feet,

and each terminal and its port can also be at distances up to 2250 feet.

This yields a maximum host-to-terminal distance of 4500 ft, and a total

aggregate cabling distance of 18,000 feet. The Model 457B has one

LED per port to indicate data activity. For added convenience, each

port has its own pair of internal straps that allow "tip" and "ring" to be

assigned to any of the eight RJ-45 pins.

Optional 19" rack mount hardware allows two Model 457Bs to be

installed side-by-side in a single 1U rack space. Additional space is

conserved by operating the two rack mounted 457Bs from a single AC

power supply harness. Power supplies of 120 or 240 volts are

available for both stand alone and rack mount units.

4.0 INSTALLATION

After the internal jumpers are configured for your equipment, you

are ready to connect up the Model 457B. This section explains how to

connect the host and terminals to the Model 457B in a star topology

using twisted pair cable.

4.1 CONNECTION TO THE HUB

Host Connection—The host port of the Model 457B allows RJ-45

or terminal block connection of a single twisted pair cable. The

maximum distance between the Model 457B and the host is 2250 feet.

Only one host may be connected to the hub at a time.

Terminal Connections—RJ-45 ports 00 - 06 on the Model 457B

allow connection of up to seven terminals using single pair cable. The

maximum distance between the Model 457B and each terminal is 2250

feet. Note: Pin-outs of RJ-45 cables must match the pin configurations

chosen for the Model 457B's ports (see Section 3.0 for more details).

4.2 CONNECTION TO HOST AND TERMINAL HARDWARE

Most AS/400 and System 3X hardware is equipped with twinax

ports, and is set up to communicate over twinax cable. In order to

communicate over a single twisted pair, you must use a twinax to

twisted pair adapter or "BALUN" at each host and terminal connection.

The Patton Model 410 Series Twinax Balun is 100% compatible with

the Model 457B, and is highly recommended for this application. Model

410 baluns are available for RJ-11, RJ-45, or terminal block twisted pair

connection. Figure 4 (below) illustrates wiring for a star network using

one Model 457B hub and eight Model 410 baluns.

3. On the Model 457B PC board (see figure 2, below), locate the

jumper blocks corresponding to each RJ-45 port. They are

labeled JP1 - JP8. As figure 3 (below) shows, each jumper

block has 16 pins and two jumpers.

4. Having located the jumper blocks for the ports you need to re-

configure, set the jumpers for TIP and RING according to the

table below. For example, placing the TIP jumper on jumper

pins 5 and 6 activates RJ-45 pin 3. Placing the RING jumper

on jumper pins 11 and 12 activates RJ-45 pin 6. The resulting

configuration for that RJ-45 port would be TIP-3, RING-6.

3 & 4 ...................................2

5 & 6 ...................................3

5. After you have repositioned the jumpers, slide the PC board

back into the case and replace the two Phillips screws.

5.0 OPERATION

Having connected the host and terminal cables to the Model 457B,

you are ready to operate the unit. This section tells how to power the

unit, and how to read the port status LED indicators.

5.1 POWER UP

There is no power switch on the Model 457B. To apply power to

the unit, plug the AC adapter into one of the two rear jacks (see figure

5, below) and then into a wall outlet. The front panel "Power" LED

should glow yellow when power is applied. The port status LEDs

should be off if the host and terminals are not yet powered up.

5.2 "PORT STATUS" LED INDICATORS

As figure 6 (below) illustrates, there is a status LED for each port

on the Model 457B. Having followed the normal start-up procedures for

your system, the host port LED should glow faintly red and each active

terminal port's LED should glow faintly green. Inactive ports should not

show any LED activity. When data activity is occurring on a port, its

LED should glow brightly. Failure of a particular port's LED to behave

as described here may indicate a problem with the cable connection or

with the host/terminal hardware.
